blood flow through the heart

Right atrium
deoxygenated blood enters the heart here, it contains three vessels
Superior vena cava
first vessel deoxygenated blood enters in the Right atrium. Blod then travels to the inferior Vena Cava
Inferior Vena cava
Deoxygenated blood travels from the superior vena cava to here and then on to the coronary sinus
Coronary sinus
deoxygenated blood flows from the infereior Vena Cava to here, then on to the right atrium
Tricuspid valve
valve which is between the Right atrium and the Right ventricle
Right ventricle
Where deoxygenated blood flows through the tricuspid to here and then exits through the pulmonary semilunar valves
pulmonary semilunar valve
deoxygenated blood travels through here from the Right Ventricle and goes to the pulmonary trunk
pulmonary trunk
deoxygenated blood travels to here from the pulmonary semilunar valves to the pulmonary arteries
pulmonary arteries
deoxygenated blood travels from the pulmonary trunk to here then on to the lungs
pulmonary veins
oxygenated blood travels to here from the lungs and then continues on to the left atrium
left atrium
oxygenated blood travels to here from the 4 pulmonary veins and exits through the mitral valve (bicuspid valve)
mitral valve (bicuspid valve)
oxygenated blood comes through here from the left atrium to the left ventricle
left ventricle
this area forms the apex of the heart, it receives oxygenated blood from the mitral valve (bicuspid valve) and it exits through the aortic semilunar valve
aortic semilunar valve
oxygenated blood comes here from the left ventricle and then exits to the ascending thoracic aorta.
